头发是由足少阴肾经的血液所滋养的。如果血气旺盛，头发就会长得长且美观；如果血虚量少，头发就长不长，需要用药物调理治疗，使其生长。
足少阴肾经的血液，在外部滋养头发。如果血气旺盛，头发就会光亮润泽；如果血气虚弱，血液就不能滋养头发，所以头发就没有光泽。
足少阴肾经的血液，在外部滋养头发。如果血气旺盛，头发就会滋润黑亮；如果血气枯竭，不能荣养头发，就会导致头发变黄。
足少阳胆经的血液，在外部荣养胡须。如果血气旺盛，胡须就会美观且长；如果血气虚少不足，不能在外部荣润，所以导致胡须（生长不良）。
足太阳膀胱经，其经脉起于目内眦，上行至额部，交会于头顶。如果血气旺盛，眉毛就会美观且有毫毛；如果血气少，眉毛就会难看。眉毛被风邪所伤，就会脱落，这都是因为血气受损，不能荣养，所以需要用药物使其再生。
头发的生长，是靠血气滋润养护的。如果被火烧伤的地方，疮痕致密，气血就会下沉，不能宣通腠理，所以头发（不再生长）。
足少阴肾经的血气，其荣华表现在头发上。足太阳膀胱经的血气旺盛，眉毛就美观；足少阳胆经的血气旺盛，胡须就美观；足阳明胃经的血气旺盛，头发就美观；手阳明大肠经的血气旺盛，嘴唇上方的胡子（髭）就美观。各条经络的血气旺盛，眉毛、唇上须、胡须、头发就会美观润泽。如果血气虚少枯竭，头发就会变黄、变白、憔悴或脱落。如果风邪侵袭经络，血气发生改变，就会产生异常的毛发乱生，这时需要用药物外敷，使其不再生长。
普通人肚子里都有九种寄生虫，遇到血气虚弱时，它们就能侵蚀身体。蛲虫发作时，最容易生疮，进而形成疽、癣、（原文缺字）、疥等病症，无所不为。所说的白秃病，都是由此虫引起，指头上生疮有虫，白色痂皮非常痒，上面的头发也一起脱落不生，所以称为白秃。
这是由于头部的疮疡，虫子啃食导致头发脱落，没有白色痂皮，但有渗出液，皮肤发红且痒，所以称为赤秃。
Hair is nourished by the blood of the Foot-Shaoyin Kidney Meridian (Zu Shao Yin Shen Jing). When Blood and Qi are abundant, hair grows long and beautiful; if Blood is deficient and scanty, hair fails to grow long, requiring medicinal treatment to promote growth.
The blood of the Foot-Shaoyin Kidney Meridian externally nourishes the hair. When Blood and Qi are abundant, hair becomes lustrous and smooth; if deficient, Blood cannot nourish the hair, resulting in a lack of luster.
The blood of the Foot-Shaoyin Kidney Meridian externally nourishes the hair. When Blood and Qi are abundant, hair becomes moist and black; if exhausted, it fails to provide prosperity to the hair, causing it to turn yellow.
The blood of the Foot-Shaoyang Gallbladder Meridian (Zu Shao Yang Dan Jing) externally prospers the beard. When Blood and Qi are abundant, the beard becomes beautiful and long; if deficient and insufficient, it fails to provide external moisture and prosperity, leading to [impaired beard growth].
The Foot-Taiyang Bladder Meridian (Zu Tai Yang Pang Guang Jing) originates from the inner canthus of the eye, ascends to the forehead, and intersects at the vertex. When Blood and Qi are abundant, eyebrows become beautiful with fine hairs; when scarce, eyebrows appear coarse or poor. If eyebrows are injured by Wind Pathogen (Feng Xie), they fall out. All these cases result from damage to Blood and Qi, failing to nourish, thus requiring medication to stimulate regrowth.
The growth of hair depends on the moisturizing and nourishing action of Blood and Qi. In areas burned by fire, if scar tissue becomes dense, Blood and Qi sink downward and fail to circulate through the Couli (pores and interstices), so hair does not grow.
The splendor of the Blood and Qi of the Foot-Shaoyin Kidney Meridian manifests in the hair. Abundant Blood and Qi of the Foot-Taiyang Bladder Meridian result in beautiful eyebrows; abundant Blood and Qi of the Foot-Shaoyang Gallbladder Meridian result in a beautiful beard; abundant Blood and Qi of the Foot-Yangming Stomach Meridian (Zu Yang Ming Wei Jing) result in beautiful scalp hair; abundant Blood and Qi of the Hand-Yangming Large Intestine Meridian (Shou Yangming Da Chang Jing) result in beautiful mustaches. When Blood and Qi of all meridians are abundant, eyebrows, mustaches, beards, and scalp hair are beautiful and lustrous. If deficient, scanty, or exhausted, they turn yellow, white, wither, or fall out. If Wind Pathogen invades the meridians, altering Blood and Qi, abnormal and ugly hair may grow randomly, requiring topical application of medicine to prevent such growth.
All ordinary people harbor nine types of parasites within the abdomen. When Blood and Qi are deficient, these parasites can invade and consume bodily resources. The activation of Ascaris lumbricoides-like worms (Nuo Chong) most readily causes sores, leading to conditions such as carbuncles (Ju), tinea (Xuan), [missing character], and scabies (Jie), committing various evils. The condition known as White Baldness (Bai Tu) is caused by these worms, referring to sores on the head with worms present, very itchy white crusts, and the subsequent loss and non-regrowth of hair above them.
This condition arises from head sores where worms feed, causing hair loss without white crusts but with exudate, red skin, and itching, hence termed Red Baldness (Chi Tu).
